Can someone please help me in simplifying the following:
y= -2(x/2)^2 - 15(x/2) - 22
I'm having problems with an assignment question because I can't remember how to do this one step... its been awhile since I took math.
Thanks.

From $\displaystyle y=-2(\frac{x}{2})^2 - 15(\frac{x}{2})-22,$ perform the squaring and rewrite as
$\displaystyle y=-\frac{2x^2}{4}-\frac{15x}{2}-22,$ express in common denominator as
$\displaystyle y=\frac{-x^2-15x-44}{2}$ and clean up the signs to get
$\displaystyle y=-\frac{1}{2}(x^2+15x+44)$
